04 Getting started
Unlike pneumatic-based bioprinting, this technique results in small droplets instead of filaments. The translational speed of the bioprinting
process will affect the pitch between droplets. A low speed might result in the droplets merging together or aggregating, while a high speed will
result in a larger distance between droplets.
The EMD Printhead includes a noncontact nozzle and a contact nozzle. The contact nozzle must be calibrated to the height of the surface, while
the noncontact nozzle must be calibrated between one and three centimeters away from the surface. The contact nozzle has a needle which can
extrude droplets or filaments depending on the parameters set.
In addition, EMD bioprinting can be used in combination with other extrusion techniques to coat or place specific cell patterns.
